Communication SchemeCommunication Scheme

Two games talk to each other over Two games talk to each other over the TCP sockets.the TCP sockets.

At start up, the game will act as a At start up, the game will act as a client and search for a server to client and search for a server to connect to.connect to.

After 2 Seconds, if no server is found, After 2 Seconds, if no server is found, client connection times out. The client connection times out. The game switches to server mode and game switches to server mode and waits for an incoming connection.waits for an incoming connection.

After the connection is established, After the connection is established, the server will have the option to pick the server will have the option to pick a color to play, the client will play the a color to play, the client will play the opposite color.opposite color.

Three Types of CommandsThree Types of Commands

After the server picks a color to play, it will send a After the server picks a color to play, it will send a command with the message, “PLAYERcommand with the message, “PLAYER color color”, ”, so client can be setup to play opposite color.so client can be setup to play opposite color.

During game playing, when a player presses a During game playing, when a player presses a key, it will send out a command with message key, it will send out a command with message “KEYCODE “KEYCODE numnum”, where ”, where numnum represented represented integer value of key pressed.integer value of key pressed.

After two players finish a round, any player can After two players finish a round, any player can press restart command, it sends out “RESTART” press restart command, it sends out “RESTART” message to reset game board to initial state for message to reset game board to initial state for both players.both players.

A sensor mote after receiving first “Route Setup” A sensor mote after receiving first “Route Setup” message, it sets the sender of that message as message, it sets the sender of that message as its parent, and broadcasts out “Route Setup”.its parent, and broadcasts out “Route Setup”.

After “Route Setup” message flooded through After “Route Setup” message flooded through the network, each sensor mote can be able to the network, each sensor mote can be able to send its measured value to the base mote by send its measured value to the base mote by first transmitting it to its parent. Its parent in turn first transmitting it to its parent. Its parent in turn will forward data to parent of its own and data will forward data to parent of its own and data will eventually reach the base mote and be will eventually reach the base mote and be displayed on PC.displayed on PC.
